DVI & Touch via USB
Digital Video Monitor GT-1P Series
GT-1P series is an embedded touch monitor designed to smoothly integrate into any project. The mounted FLETAS® touch panel gives the GT-1P series high touch sensitivity to operate accurately in demanding environments.
PC / SBC Ready
DVI (Digital Visual Interface) is transmitted to the GT-1P through an HDMI type-A connector. This connector accepts unencrypted digital video signal and outputs raw 24-bit pixel data to the display (HDCP not supported).
Touch is sent through HID compliant USB and I2C interfaces. No drivers necessary.
Touch Sensitivity and display brightness can be controlled by simple commands.
|Single/Multi Touch Mode||0x1F, 0x50, 0x01, [Mode]|
|Touch Panel Data Transmit||0x1F, 0x50, 0x20, [ON/OFF]|
|Touch Parameter Setting||0x1F, 0x4B, 0x70, [Op.],[Parameter]|
|Back-light Brightness||0x1F, 0x58, [Level]|
|Memory Switch Setting||0x1F, 0x28, 0x65, 0x03, [SW.],[Data]|
|Memory Switch Data Send||0x1F, 0x28, 0x65, 0x04, [SW.]|
|Prodcut Status Send||0x1F, 0x28, 0x65, 0x40, [Op.], [Parameter]|
For the details, please refer to the module’s respective specification.
Extended Display Identification Data (EDID) is supported to make Plug & Play (auto display settings) with the EDID supported device.
Touch via Serial Communication
Touch data can also be obtained through I2C and UART using the simple commands seen on the left. So, if USB communication cannot be achieved, any micro-controller with UART or I2C can read touch data and change the module’s settings. For more information, check the module’s respective full specification.

This application note describes GT-1P module’s touch panel features, USB communication setting up guide, touch sensitivity reference, and more useful information. To install the GT-1P module into your application smoothly, please refer this document first.
GT-1P Communication on Linux
For USB communication, we have used libusb.h (an open source library) and a generic USB driver. This web-page describes these methods in detail and provides example code to get you started.
Software Development Support Tool
This guide shows solutions to frequently asked questions and common problems that users may encounter while using Noritake GT series modules.
The following contains our test results while testing the GT800X480A-1303P module. Actual results may vary with specific PC environments.

|Touch via USB||Command Execution via USB|
|Windows 7||The display works as a generic monitor. No driver required.||Touch works as a Human Interface Device (HID) compatible device and is recognized as a Digitizer or Mouse.||The latest WinUSB driver may be required.|
|Windows 8.1 and 10||The display works as a generic monitor. No driver required.||Touch works as a Human Interface Device (HID) compatible device and is recognized as a Digitizer or Mouse.||The module works with the generic WinUSB driver. No additional drivers required.|
|Raspberry Pi 3 with Raspbian, Ubuntu MATE||EDID is not supported. “hdmi_cvt 800 480 60 6 0 0 0” needs to be added to “/boot/config.txt” for pixel perfect display.||Touch works as a Human Interface Device (HID) compatible device and is recognized as a Digitizer or Mouse.||Need a USB communication library. Only libusb.h has been confirmed so far.|
If the screen is not displayed correctly, please try this configuration line in the Raspberry Pi’s config.txt file.
hdmi_cvt 800 480 60 6 0 0 0
Upon reboot, the video signal will have changed to fit the display’s resolution.
No additional video signal configuration lines are needed to create a pixel perfect image.
GT Product Features
FLETAS® Metallized Projective Capacitive Touch
Two metallized layers(x-y) are overlaid onto an LCD screen. These thin-film metallic panels have a lower impedance than typical ITO** touch panels. This allows for a higher S/N ratio, wider touch sense margin, and better overall sensitivity.

** ITO = Indium Tin Oxide
Each module has a high brightness TFT ranging from 950-1000cd/m2*.
* Actual brightness range: 810-850cd/m2.
Variable projection radius. Tested up to 5mm acrylic and *15mm glass overlay without aﬀecting touch response under factory conditions.
Configure touch sensitivity by simple commands for your build with tolerance for gloved users and water interface.
Allow for gesture control and handles up to 10 concurrent touches at a time.
